Comprehensive display of high precision metal cutting and grinding technology from Hardinge Inc. at AMB

AMB 2018:  Stuttgart, Halle 5, Stand B80.

The latest Kellenberger 100 platform concept cylindrical grinding machine features alongside two Hardinge Super Precision turning and turn/grinding CNC centres on the Hardinge Inc. stand at the forthcoming AMB 2018 exhibition.

Since its introduction in 2017, the innovative Kellenberger 100 concept has been well received, fulfilling the objective of developing a high-performance, cost effective cylindrical precision grinder.  While adopting a highly flexible modular design, the machine makes use of technology from Kellenberger’s Vista and Vita machine ranges, the Tschudin T25 and the Jones & Shipman Ultramat CNC and Ultragrind 1000 – all tried and trusted machines in their respective sectors.

In terms of functionality the new 100 concept delivers a range of configuration alternatives to meet the widest range of grinding applications. Modular construction based on a common platform is designed to reduce machine build time yet accommodate numerous ‘standard’ options with an excellent price/performance ratio for the end user.

Three important features distinguish the new 100 machine series:

First, an innovative, collision-free, compact wheelhead solution.  This is a new, compact wheelhead system with integral motor spindles and a reinforced casing for larger wheel diameters when internal grinding. There is a choice of 10 wheelhead variations to ensure the optimal machine configuration based on the components to be processed.

Secondly, the enhancement of performance parameters:

A higher grinding wheel drive power increases productivity while the newly designed Z guideway produces higher profile precision from the C axis, again enhancing precision when non-circular grinding.

Finally, the service-friendly machine concept:

Kellenberger’s service teams were involved in the design and optimisation of the machine. This impacts on faster maintenance and service operations and optimum accessibility of maintenance-intensive components is assured.

The Kellenberger machines feature the latest Fanuc 31i CNC controls with 19″ touchscreen guidance system on an operator friendly, intuitive touchscreen panel. An option is the newly designed cycle programming or workpiece-related graphic programming.

Perfect Finish in one operation

Hardinge Super Precision turning and turn/grinding machines have a reputation for holding the tightest tolerances when manufacturing hard to manufacture parts.  The latest T-Series CNC lathes from Hardinge not only continue this long tradition but achieve new standards of precision and capability.

At AMB two machines will be operational – the Hardinge Quest GT 27 SP turn/grind centre and the T42 SP turning centre.

The Hardinge Quest GT 27 SP is a combined turning and grinding centre, specially designed for high precision manufacturing of complex parts.

It features a 10hp, 8,000rpm main spindle with 27mm bar capacity. However the GT 27 SP can be equipped with a “Big-Bore” spindle to handle up to 42mm bar capacity. The headstock assembly features heavily ribbed construction, allowing minimal heat retention and optimum part size control.

The machine can be equipped with up to four grinding spindles that makes the machine ideal for producing high quality, high precision parts depending on machine configuration. The grinding spindles can be 30,000, 50,000, 80,000 or 100,000 rpm speeds with surface finishes (turning) of .20 micron and exacting part roundness of .38 micron achievable. The lathe can produce continuous machining accuracy of 3 microns.

The Hardinge T 42 Super-Precision turning center is ideally suited to productive and reliable manufacturing.

This machine delivers optimum precision and accuracy and is ideal for two axis high precision machining or complex multi-tasking operations that require a high level of super precision, delicate part handling and parts made complete in a single setup.

The T 42 SP features a 15hp, 6,000rpm A2-5 collet ready spindle with 42mm bar capacity and a 16 station turret offers a half station index for up to 32 tools.

In production a high level of precision/part surface finish is maintained at .15 micron, with part roundness at .25 micron and continuous part accuracy within .3 micron.  The overall axis repeatability is .76 micron.
